Bovine Serum as an Alternative to Control Serum for Total Protein Levels

Total protein describes the liver's ability to synthesize proteins and metabolize substances in blood. Bovine serum can be used as a control material because total analyte bovine blood is almost identical human serum. The researchers intend determine homogeneity stability of with addition 7,5% ethylene glycol preservative after being stored for 12 weeks at -20°C an alternative levels. This research survey analytics using one-group pretest-posttest design. Data analysis ISO 13528 2005 calculations. From examination level serum, value Xr – Yr = 0.23817, which where meets test criteria according | - <0.36, that 0.23817 <0.91585. content was homogeneous stable 7.5% -20oC weeks.
